Description

Technical Field

[0001] This utility model relates to the field of mold transfer technology, specifically a mold hoisting device. Background Technology

[0002] When moving mold steel, it is necessary to hoist the mold steel body to facilitate the transfer and repositioning of the mold steel. Furthermore, the mold steel can be effectively positioned during the transfer process to prevent it from loosening and falling off.

[0003] Utility model CN219098500U discloses a mold hoisting device, comprising: a hoisting box with an open top, a movable plate, and several limiting and fixing components; one side of the hoisting box is open to form a mold channel, and the bottom of the mold channel is rotatably provided with a movable plate that can cover the mold channel via a horizontal pivot. The side of the movable plate away from the pivot can rotate to rest against the ground, and a plurality of at least partially protruding and freely rotatable spherical balls are evenly embedded on the side of the movable plate away from the ground. The side of the movable plate in a vertical state can be locked onto the hoisting box. This device overcomes the problems of existing devices, where the mold to be hoisted needs to be moved to a hoisting platform, and unloading also requires handling, which is time-consuming and labor-intensive. Furthermore, the mold is not additionally limited and fixed on the hoisting platform and is directly placed in the mold placement space, resulting in a lack of stability during hoisting and reduced safety.

[0004] However, the above-mentioned existing technology still has shortcomings in use: since the mold is mainly made of steel, it is relatively heavy. In order to transfer the mold into the box, the above-mentioned existing technology first needs to lift the mold onto the movable plate, and then push the mold into the box. Moreover, when it is hoisted to the target position, it is necessary to process the mold to push it out of the box. Therefore, there is a problem that it is laborious to manually transfer the mold.

[0005] Therefore, this utility model provides a mold hoisting device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mold hoisting device to solve the problems mentioned in the background technology. This utility model has the advantages of making the operation of molds entering and leaving the hoisting box more convenient and labor-saving.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold hoisting device, including a hoisting box with an opening on one side, two sliding beams respectively close to the two sides are provided at the bottom of the hoisting box, the upper ends of the two sliding beams are fixedly connected by a gantry frame, a lifting shaft is provided at the top of the gantry frame, a hook is fixedly connected to the bottom of the lifting shaft, and locking components are also provided on both sides of the hoisting box located on one side of the sliding beams.

[0008] Furthermore, there are two lifting shafts, which are set as crossbeams passing through the gantry frame, and the two lifting shafts are fixedly connected by a connecting plate.

[0009] Furthermore, the connecting plate is located below the crossbeam, and a drive shaft is screwed through and connected to the middle of the crossbeam. The bottom of the drive shaft is rotatably connected to the middle of the connecting plate.

[0010] Furthermore, a handle is welded to the top of the drive shaft.

[0011] Furthermore, a guide shaft is fixedly connected inside the hoisting box on the side opposite to the opening, and a slide rail is provided at one end of the sliding beam, which is sleeved on the outside of the guide shaft.

[0012] Furthermore, the locking component includes a screw and a sleeve, one end of the sleeve is fixedly connected to one side of the crossbeam, and the screw passes through both sides of the screw-on hoisting box and one end of the screw is fixedly connected to a pin that engages with the sleeve.

[0013] Furthermore, the bottom of the sliding beam is fixedly connected to a support pile located outside the opening of the hoisting box, and the bottom of the support pile is connected to a roller.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the hoisting box has an opening on one side, and a gantry frame is installed inside the hoisting box. A sliding beam is installed at the bottom of the gantry frame and is slidably connected to the hoisting box. A lifting shaft is installed at the top of the sliding beam, and a hook is installed at the bottom of the lifting shaft. By pushing the gantry frame, the mold lifted by the hook can be moved into the hoisting box. Compared with the prior art, this has the advantage of saving more effort in loading and unloading molds.

[0016] 2. In this utility model, a locking component is provided inside the hoisting box on one side of the sliding beam. When the sliding beam is fully inserted into the hoisting box, the locking component can lock the sliding beam. Then, the lifting shaft is controlled to descend so that the bottom of the mold contacts the bottom inside the hoisting box. At this time, the mold is supported by the hoisting box and limited by the hook, which greatly improves the stability and safety of hoisting. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a mold hoisting device, including a hoisting box 1. The top of the hoisting box 1 is provided with a connecting ring near the corner. The connecting ring is connected to the hoisting rope of the crane. The hoisting box 1 has an opening on one side, which is the channel for the mold to enter and exit the hoisting box 1. When in use, a side door can be installed on one side of the opening. The side door opens by rotating laterally, and the opening is blocked when the side door is closed. The side door is connected to the hoisting box 1 through a pin when closed. The bottom of the hoisting box 1 is covered with an anti-slip buffer pad, and the inner side of the hoisting box 1 is welded with an anti-collision pad.

[0023] The bottom of the hoisting box 1 is equipped with two sliding beams 2, one near each side. Specifically, a guide shaft 101 is fixedly connected to the side of the hoisting box 1 opposite to the opening. One end of the sliding beam 2 has a slide rail 21 that fits outside the guide shaft 101. When the sliding beam 2 slides, one end can extend out of the opening of the hoisting box 1. The upper surfaces of the two sliding beams 2 are fixedly connected by a gantry frame 3. When the sliding beam 2 slides, it can drive the gantry frame 3 to move to the outside of the hoisting box 1. A lifting shaft 4 is provided at the top of the gantry frame 3. A hook 5 is fixedly connected to the bottom of the lifting shaft 4. When the lifting shaft 4 moves up and down, it can drive the hook 5 to move up and down. In use, the hook 5 is connected to the lifting ring on the mold through a sling.

[0024] In this embodiment, there are two lifting shafts 4, which are set through the crossbeam 31 on the gantry frame 3. The two lifting shafts 4 are fixedly connected by a connecting plate 8. The two lifting shafts 4 are connected to the two lifting rings on the mold by two hooks 5, which improves the stability of the mold after lifting.

[0025] Furthermore, the connecting plate 8 is located below the crossbeam 31, and a drive shaft 9 is screwed through and connected to the middle of the crossbeam 31. Specifically, a threaded sleeve can be welded to the middle of the crossbeam 31 and fitted onto the outside of the drive shaft 9. The drive shaft 9 has threads that fit the threaded sleeve. The bottom of the drive shaft 9 is rotatably connected to the middle of the connecting plate 8. When the drive shaft 9 rotates, it can use the screwing force to drive the two lifting shafts 4 to move up and down through the connecting plate 8. A lever 91 can be welded to the top of the drive shaft 9. The lever 91 is a drive component for manually controlling the rotation of the drive shaft 9.

[0026] The hoisting box 1 is also equipped with locking parts 7 on both sides of the sliding beam 2. The function of the locking parts 7 is to lock the sliding beam 2. Specifically, after the gantry 3 enters the hoisting box 1, the locking parts 7 can lock the sliding beam 2 to prevent it from moving freely, thereby preventing the mold from sliding sideways in the hoisting box 1.

[0027] In this embodiment, the locking component 7 includes a screw 71 and a sleeve 72. One end of the sleeve 72 is fixedly connected to one side of the crossbeam 31. The screw 71 passes through both sides of the hoisting box 1 and one end of the screw 71 is fixedly connected to a pin 711 that engages with the sleeve 72. In a specific implementation, the sleeves near the opening can be welded to both sides of the hoisting box 1. The sleeves are fitted over the outside of the screw 71. When the screw 71 is rotated so that the pin 711 is inserted into the sleeve 72, the crossbeam 31 is locked.

[0028] In this embodiment, the bottom of the sliding beam 2 is fixedly connected to a support pile 102 located outside the opening of the hoisting box 1. The bottom of the support pile 102 is connected to a roller 103. When in use, the roller 103 contacts the ground and plays the role of supporting the sliding beam 2, so that when the sliding beam 2 extends to bear the load, it will not cause the entire hoisting box 1 to tilt. At the same time, it makes the movement of the sliding beam 2 relative to the hoisting box 1 smoother.

[0029] Working principle: When a mold needs to be hoisted from the ground, a crane is used to hoist the hoisting box 1 to one side of the mold using a hoisting rope, ensuring that the opening of the hoisting box 1 is opposite to the mold. Then, the gantry 3 is manually pulled outward, and the sliding beam 2 moves outward along the guide shaft 101. At the same time, the roller 103 rolls on the ground. When the hook 5 is above the mold, the hook 5 is connected to the lifting ring on the mold through the sling. Then, the drive shaft 9 is manually turned by the lever 91. The drive shaft 9 rises and drives the lifting shaft 4 to rise through the connecting plate 8. At this time, the mold is lifted and lifted off the ground. Then, the gantry 3 is pushed into the hoisting box 1, and the roller 103 rolls. At the same time, the sliding beam 2 slides along the guide shaft 101. After the mold enters the hoisting box 1, the screw 71 is turned so that the pin 711 at one end is inserted into the sleeve 72. At this time, the sliding beam 2 is locked. Then, the drive shaft 9 is controlled to rotate in the opposite direction so that the bottom of the mold contacts the bottom of the hoisting box 1. Finally, the side door at the opening of the hoisting box 1 is closed for safe hoisting.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
